I To all whom it may concern:

Be it known that l, ABRAHAM Fnrnnron,

a citizen of the United States, residing at ,Demarest, in the county of Bergen, State of New Jersey, have invented a new and use tul Non-Slnddmg Attachment for Wheel- Tires, of Which the following 1s a spcc1l1cation.

' My invention consists of a non-skir'lding attachment for a wheel formed of means adapted to be imposed on the circumference of the tire thereof, and secured thereto, and

having a tread which may be termed roughshod, so as to engage with and grip a road bed, especially when the latter is icy, greasy, wet, or in any other condition that would cause or allow the wheel toskid or slip, said means also protecting a tire from injury and not interfering withthe resiliency of the tire when composed of rubber and appliable, alsoto a telly of a wheel of a wagon, carriage, or other vehicle.

Details of construction are also provided as will be hereinafter described.

The invention is satisfactorily illustrated 1n the accompanying drawing, but the unportant instrumentalities thereof may be varied, and so it is to be understood that. the invention 1s not limited to the specific details shown and described.

Figure 1 represents a side elevation of a portion or a :nonskidding attachment for a wheel embodying my invention and a corresponding portion. of the wheelto which the attachment is applied.

l 5?. represents a transverse section on an enlarged scale, on line 242 Fig 1.

Fig. 3 represents a face view oi a portion of the attachment on an enlarged scale.

Fig. 4 represents a longitudinal section of a portion thereof on line 4r-'l l ig. Fig. .5 is a detail transverse section illustrating a modification in which the plate shown has a transversely-extending channel tor the reception of an attaching strap.

Fig. 6 is a detail broken perspective view showing another modification in which the' attaching strap is riveted directly to the pl rte.

Fig. 7 is a detail. transverse section illusthe application of a plate coned in accordance with my invention to lily of a Wheel.

Similar numerals of reference indicate corres mnding'parts in the figures.

Referring to the drawings.

1 designates a rubber or resilient tire of an automobile wheel. 2 desigmltes the rim or. telly portion thereof, 3 the spokes, 'and the hub thereof, which features of themselves as members of an tllltOll'lObllQOl otheriv ehicle are well known. e

5 designates segmental plates which disposed upon the outer periphery or tread portion of the tire around the same and hairing outwardly projecting spurs 01' teeth 6 torn'iing an anti-skidding attachment for the wheel, it being noticed that in the rotation of he wheel said spurs are adapted to engage the road bed and grip with the same and so prevent the skidding of die wheel.

The plates and their spurs may be formed of cast or wrought metal or other material, or of sheet metal, the spurs b ing punched out of thesame.

The plates while conforming to the circumferential curve of thetire conform also to the, transverse curvature of the latter, both as shown in Fig. 2, or the plates 7 may be made straight in, cross section as shown, so as to be fitted directly upon and secured to the telly 8 of a wagon or other vehicle wheel, as shown in Fig. 7

In order to connect the plates 5 with the tire 1, said plates are formed on the sides thereof with the loops 9, as in Figs. 1

and 2, and to said loops or eyes are riveted as at '10 the straps 11 and 12, the straps 12 being passed around one side of the tire, and under and across the rim 2, and then engaged with the straps 11, by the buckles l3, andthus the plates may be held firmly in position on the tire, and conveniently removed therefrom when so desired.

lhe number of plades and of the fasten: ing devices may be increased as desired, it being noticed also that the ends of the plates sllllicicntly approach each other to break joints and form an articulation of plates around the tire, while preserving the con' t-inuity of the attachment. 'and preserving er'ing or inclosing sultieiently the tread portion of the latter, so as to guard the same trourbcing struck and injured by obstructions on the roadbed. and as spurs are made preferably hollow they take better hold of the roadbed and allow air to enter, thus keeping the spurs and consequently the attachment in cool condition. y

The plates lie flat and smooth on the tire l and so protecting the latter-from objects on the road bed that strike and injure the tire, and also as they cover the tire to that extent they prevent blow-outs, thus adding durability and life to the the Air may enter the same so as to keep the plates and the spurs whereby they are disposed spurs and circulate around the" and the tire from beocmiing warm and heated. The spurs may be cast, or st ruclc up solid with the plates with rough-or pointed surfaces or edges as desired. .lhe plates being separate produce an articulation of the attachment. allowing certain play at the terminals of the plates without alter-ting the resilient nature, of the tire owing to the articulation.

Havin thus described my invention what I claim as new'and desire to secure by Let/-- ters Patent, is:

A non-skidding attachment for tires, eon:- prising a, metallic plate. applicable to the tread portion of a tire and baring openings scattered throughout its area. and also having outwardly-extending flanges grouped about and adjacent to eaeh opening and pointed; the openings and their comple mentary flanges beingarranged in series lengthwise and crosswise oi the plate and being also arranged in staggered relation close together.
